LIQUID-AGITATING DEVICE;

Specification of Letters Patent. Patented Aug, 47 1915,

Application led April 21,1914." Serial 110.833,4915. v

ments ina common type of egg beaters or,

means of peculiar form whereby to `more thoroughly break up or agitate the fluid or substance operated onV byy the beater, than is practicable in the use of similar, devices heretofore employed. Vith` this in View I utilize agitating means comprising frames rotatable in different paths though fairly close proximity, each frame consisting of a piece of metal notonly bent peculiarly to afford a maximum amount of agitating sur-lvr face but, of greater importance, formed `with specially arranged corrugations orjdeiiected portions adapted', ,to positivelyy throw rthe liquid or other substance to be agitated in opposite directions'fro'm the frame in paths intersecting thepaths of movement of the adjacent agitating frame. In fact, inl acf tualpractice the agitating frames in' acting on the liduid tend to throw the portionsof the latter kin intersecting paths and in this way a veryhigh degree of efficiency is obtainedy in breaking up' ,the liquid, vso to speak, to secure the greatestvfpossibleamtating effect.

Another primary object of my invention has been to provide a beater `or similar agitating rdevice for various purposes,the construction of which is so simple as to be eX- ceedingly cheapto manufacture, vpractically all of theoperating parts being capable 'of being` stamped out of metal. n f l Y i A third important object of the inventionhas been to so devise rtheagitatingrr contrivance as to facilitate the separation of the various ,parts` thereof for purposes fof cleaning, and admitting of very quick replacement in coperative relation. j j

l/Viththe above and other objects in view the advantages' of the, invention willy be fully appreciated on reference to the followingy detailedldescription and to the accompanying drawing in which:

Figure 1 `is side view of a device embody,-

ing` the essential features of the invention.

Fig. 2 is a vertical sectional view on the linek 2-2 of Fig. l. Fig. 3 is a plan view of the blank piece of metal from which the handle is formed. l Figs. 4 and 5- are perspective and sectional views respectively, showing moreV clearly the method of forming the corrugated or deiiecting elements of the agitating members. F ig. 6 is a section-on the line 6-6 of Fig. 1. Y j

In the drawings A denotes the shank or body of the egg beater, B the handle, and C and D the agitating members or frames.- The' shank A is preferably made froma piece of sheet metal the lower end of which is bent laterally to form as bea-.ri-nig arm- 1 andethere being three rother arms 2, 8 and 4, bent outward from the body of the shank. The arms 2, 3 and 4 are preferably made `by cutting the shankA and then striking out the cut portions as seen clearly in 'Figsp 1 and 2. The, arm 2 'is adjacent the upper end of the shank and forms a stop as' wellas bearing for the upper end of a solid shaft 5 which., is suported in bearing openings formed in the arms 1, 3 and 44. VThe solid shaft doesnot directly engage the arms 1 and 4, however, being adapted to rotate i-n a hollow shaft 6 which is supported` in the bea-ring openings of said arms l and 4.. The shaft 5 projects some distance'jbeyond the lower end' of the shank A and rigidly -attached thereto, is the agitating memberjor frame D, above referred to.` On, ther other hand the hollow shaft 6 extends from a point adjacent the arml 4 anda slight distancebeyond the arm l suiiicient to' permit the attachment thereto for .rotation of the other agitating member C. TheA lower end of the shaft 5 not only passes through the lowerendof the agitating member D but also through thecorr'eSDOnding end of the agitating member G which is larger-than the member D and rotates in a path spaced member D rotates. l*

It is contemplated to employ a drive gearV c Erfcrv operating thefmembers C and D, said A gear E being preferably formed with openings'arranged annularly thereof, vin which openings the teeth of pinions 7 and 8 engage, the pinion 7 being ycarried by the Y shaft and the Vpinion 8 by the hollow shaft 6; Saidv shafts 5 and. 6 are preferably formedwith longitudinal grooves and theV plnions are provided with integral projections or key elements seated 1n the grooves of the respective shafts. to Yfix the Vpinions A upon said shafts for' rotation therewith.

' l0 the movement of the gear E istransmittedto the pinions17 and 8, their respec- Thegear E is mounted on a stud 9 as an aXisand when being rotated by the handle y tive shafts and 6 and the respective agitat ing members D and C carried by said shafts. Injthis way" the agitating members C and D maybe rotated at high Vspeed in opposite Y directions and in non-intersecting paths, the

' operator 'grasping the handle B in one hand and'turning thegear E through the medium ofthe handle'lO grasped by the other hand. The vformation of the agitating members C and..D- is especially important, as l before f premised, each member consisting yof Va frame made from a strip of metalrarrangedV horizontally edgewise but formed at close intervals with oppositely inclined corrugat-ions l1. The corrugations llhave a unique Vaction during the rotation of the members C and D inthe flu-id or mixture to be agitated. Sincecertain alternate corrugations incline in the samedirection vand* the intermediate corrugations are oppositely inclin'edf it follows that while each agitating memberv is rotating, portionsof the fluid agitated areV forcibly thrown at abn-angle to the' general yhorizontal path in which the .memberfrotates and in `directons both up-V ward and downward in respect to said path.

i VIn this vway. not only dovthe elements 11 of each of the members 'C rand D cause kthe liquid vagitated to be thrown vin paths intersecting the parts of each member itself, but

also into paths in which said portions ofl the liquid are caused toimpinge one another by intersecting, so to speak, the liquid being thoroughlyfbroken up with a. maximum agitation under such conditions.

The above result is /subserved owing to I the fact that 4the upper and lower portions Y of each ,agitating member C and D areconne'cted bythe sides of Veachmembe'r, vwhich sides are formed of a plurality of'recurved portionsof the metal from which the parts v are made.

said sides corresponding.

ves

In other words, the sides of each member C andv D curveinwardly and outwardly anumber ofvtimes, the curvatures of I l'provideavery'simple and advantageous handle member'B la-lso'made out of sheet metal, with a view of reducing the cost of Vmanufacture of` my whole `Vcontrivance.V The blank from which the handle B is made in Fig. 8 and is composed of the' body portion which'forms the handleproperyand end portions of T-fo'rm provided withears o Awhich are bent toward one anotheryso as to embrace therebetween the upper end of the shank A. rFliese end portionsoff the handleV B are'interlocked with the shank A' owing to-themethodof bending the ears o into engagement with the shank under high pressure,rportions of the ears beingbent vinto the cut-away portion from *which` the Varm 2 is struck out-fromV theA -body of the shank. i'

When it isdesired to'separate the `parts ofthedevice for thorough cleaning, a small 'pin l2 passingy through the shaft 5 at a point above the pinion 7vis removed and the members C andD maybe pulled ci of the rated fromV the shafts, said lpinions normally operating in the clearance spaces affordedbyfthe method of striking out metal of the 'shank A. to provide the arms?) and 4,

ik' most sanitary and eiective device is provided owing to the foregoing'advantageous separability of thevparts rwhich lmay be'justy asconveniently replaced in their operative positions in an obvious manner.

Having thus described the invention, what .is claimed as new is passingv through the other bearing VVarms, aV

hollow shaft mounted in certain of said'bearing arms and having the first mentioned shaft'V passing therethrough, agitatingmembers carried by said shafts at corresponding ends of the latter, pinions 'mounted on said shafts in spaced relation at'the other corresponding ends of the same and yengaging with said gearl at portions-of the latter on c oppositesidesof its axis, means for prevventing.displacement of said shafts from the shank, and a handle carried bysaid"shank.

2. In an egg beater or the like', the combination'of aV 'shank consisting of apiece of sheet metal having its lower end bent -Y to .Y shankA'with their'respective shafts. The` pinions' and 8 will of course be thus sepa# looy form a lateral' arm and provided 'intermee j diate itsends with struck-out portions forming *other bearing arms anda'stop arm, a gear rotatable on said shank, a shaft having one end engaged vwith'l said stop arm and passing through the other bearing arms, a

hollowshaft ymounted in vcertain of said bearing arms and having the first mentioned shaft passing therethrough, agitatingmem-r the shank, and a handle carried by .saidV shank, said handle consisting of a length of sheet metal formed with oppositely extending lateral ears at each end, said ears being bent to embrace one end of the shank and interlocking with the same.

3. Agitating means of the class described comprising spaced revoluble agitating members, each member consisting of a strip formed with a plurality of lrebent superposed portions so as to constitute a series of parallel horizontally extending agitating elements, the edge of the strip at one side of a horizontal element being corrugated and at its opposite edge likewise corrugated but at intermediate transverse points whereby to form staggered corrugations, and the staggering arrangement being oppositetly formed with respect to adjacent horizontal elements to throw liquid impinged thereby in intersecting streams.

4. Agitating means of the class described comprising spaced revoluble agitating members, each member consistingv of a strip formed with a plurality of rebent superposed portions so as to constitute a series of parallel horizontally extending agitating elements, the edge of a strip at one side of a horizontal element being formed with corrugations forming alternate ridges extending above Vand below the horizontal plane of movement of the strip in revolving, and its other edge being likewise ridged but in diametrically opposite directions to the corresponding ridges rst mentioned, and the corrugations of adjacent ho-rizontal elements being staggeredly arranged whereby each element will throw upwardly and downwardly directed streams of liquid impinged thereby adapted to intersect correspondingly directed streams of an adjacent element.

5. Agitating means of the class described comprising agitating members revoluble about a common axis, said members consisting of an outer and inner frame, each frame having its sides correspondingly bent inwardly a plurality of times to form spaced substantially parallel re-curved portions extending at right angles to the axis of rotation of said frames, the re-curVed portions of said frames being formed with liquid impinging corrugations arranged oppositely with respect to each other whereby to throw the liquid in streams of intersecting paths, and means for rotating theframes.

In testimony whereof I aix my signature in presence of two witnesses.
